    Hi *

    I am attempting to tar all the subdirectories that begin with the letters a-d. The command I used was:

    tar -cvf /dev/rmt0 [a-d]*

    Looking at the process list, it shows that the shell expanded the arguments correctly:

    wbmpxdb01 / # ps -fu XPbackup
         UID PID PPID C STIME TTY TIME CMD
    XPbackup 18312 64408 2 May 29 pts/2 33:45 tar -cvf /dev/rmt0 /XPmnt brwarne clparch data ddmarqu dmbichl dmwiesn
    XPbackup 64408 72142 0 May 28 pts/2 0:00 -ksh
    wbmpxdb01 / #

    However, as I watch the output to the screen, tar is going after every subdirectory.

    I have tested this using different ranges and it always grabs all of the subdirectories.

    Can anyone explain why it might be doing this?

    TIA

    David
